As the hands got more heated, Duncan discarded the shirt and Priscilla went on the offensive. As though waiting for the piece of fabric she attacked his neck, moving downwards. The kisses again were not tender and spoke of need and desire. Sexual release the goal.
She created a trail of bite-kisses while Duncan began reclining back letting his sister work her way down. Hungrily she kissed, making marks with her teeth that would fad, Duncan hoped. She continued down, unopposed until she reached the top of his boxers.
It was a natural stopping point. Priscilla looked up at Duncan as though searching for something. Duncan only managed nodding and she continued. The kisses turned gentle but kept their lusty passion as she kissed his mass over the boxers. Duncan groaned as the heat and attention of her mouth continued on his dick.
Then, like a gate broke, she tore off his boxers, ripping them from his legs as she continued to kisses but this time on the real article, unprotected from fabric. Duncan breathed out a low groan at his sister's attentive mouth worked on him. Her kisses worked up and down his shaft and an additional groan worked its way out of his mouth as he felt her hands gently nestle his balls, massaging them.
He felt her smile on his dick, priding herself on how good she was making her brother feel. Priscilla drew back and then went forward as she took him in her mouth. Duncan felt his hips began to slowly pump back and forth as he melted. Priscilla bobbed up and down, slowly and purposefully on his cock. Her acting like a suction lock as she moved her tongue while his dick remain incapsulated in her mouth.
Duncan, meanwhile, had his eyes staring at the ceiling, knowing that if he met his sister's eyes while she was going down on him he wouldn't last a second longer. Priscilla finally detached, kissing down the shaft more last time as she sucked down at the balls, taking her time with the right one and then the left one. She leaned back staring at Duncan, a self-satisfied smirk on her face.
"You're turn," Priscilla said, lifting her leg in the air, pointing at him with her toes. Leaving no room for error that these actions were transactive and done out of mutual sexual release.
Not a big fan of feet, Duncan did not have the same attitude when his body was doing its best to propel him to have sex. He started by kissing the big toe. Immediately rewarded by a giggle from Priscilla, he pressed on. Having not retracted her toes, Priscilla watched as Duncan gave lavish care to her foot as he kissed and sucked. Priscilla, not the ticklish one between them still found the odd sensation to be oddly arousing and satisfying as he kept it up. He continued up from the foot to the heel, from the heel to the calf and up to the thigh. It was here that Duncan knew to make the big moves.
He moved the same way she had done from his neck but this time the opposite way. He kissed and after he kissed he left a small bite, the way she had done as he journeyed up her thigh. He reached her panties and noticing a wet mark, kissing gently there before traversing the other thigh leaving the same kiss and bite that he had been doing. Priscilla made groans and moans of approval and seem especially approving of the kiss at her wet mark.
Finishing up with the other thigh, he journeyed up. He ducked underneath her shirt, earning him a small squeal as he resumed the kissing and biting. As he made his way up, he used his hands to start tugging off the shirt until it came off completely freeing his sister in front of him. Seeing the metal bars in his sister's nipples, he raised a brow over at his sister who looked away, a red hue appearing on her face and seemingly appearing on her chest too. At this point he had reached the point between her breasts when he moved over and began to lick her nipple, a strong metallic taste. Sensing a sharp intake of breath he redoubled his efforts. He clamped down on the nipple bar, and began to pull it back playfully, letting the pain and pleasure play out on his sister's face as he delighted himself with her chest.
As he started to feel a spread of wetness from below where his dick had once again found itself against her crotch, Duncan journeyed back down. The kisses and bites down her stomach until he reached the edge of her panties. He pressed his mouth on the soaked fabric, letting him get acquainted with her flavor. He gripped onto the sides of her panties as he slipped his fingers into them, pulling down.
Her pussy was shaven completely, the entrance slick with anticipation and getting wetter as he peered at it. He pressed his finger to the lips, massaging them, little whimpers from Priscilla pushing him along. Bending down further he licked the pussy from top to bottom. He put his thumb up to her clit that had become readily available and begun slowly circling it. Duncan felt her hand grab his forearm as she moaned from his touch. His tongue moving slowly up and down her. His tongue lashing around her and inside her as he kept working to find the perfect tempo as he listened to her body.
Fingers closed around his jaw as he got pushed up to see Priscilla looking down at him, her eyes alight with desire.
"I want you in me."
It was a simple phrase and it had an immediate effect.
Duncan pushed himself up to her eye-level. Like the way it started they began again, kissing each other with only lust on the mind while the rubbed against each other.
A moan came from both of them as Duncan's dick found her entrance and slowly made its way in. Slick and wet, there was no resistance and Duncan found himself slipping all the way to his base. She was warm, slick, and responsive as her pussy conformed around his shape. Duncan moaned out, needing a moment having being completely swallowed up. As they both got use to filling and being filled, Duncan and Priscilla started to rock against each other moaning once again in each other.
Duncan felt it building and started moving faster, this seemed to work for Priscilla who started becoming more vocal, her hands gripping his back leaving light red marks as she scratched, her knees pressed against the sides to gain control as she pumped harder into him. Pushing underneath her thigh, Duncan pressed her down as he penetrated deeper, pumping into longer and harder strokes. He felt as Priscilla wrapped her legs around him and pulled him closer, urging him deeper.
At last, they both erupted. Priscilla bit down on his shoulder to prevent her from screaming out as she orgasmed, the muffled moan pushing Duncan even further than he already was. His orgasm came strong and he felt the flood of his spunk filling his sister as he pumped weakly as though trying to push as far inside her as possible.
They laid unmoving, Duncan on top and Priscilla below him for a few seconds before they started to move. They collected their clothes and went to the bathrooms. Priscilla moved faster getting the second floor bathroom faster, causing Duncan have to use one of the first floor ones. A common staple in the Belville household was fighting for bathrooms. Usually Priscilla won.
Duncan finished his business before splashing some water on the areas that he sweat, cleaning himself. He went back to the bedroom to see Priscilla already waiting for him already in bed. He climbed back in and laid down, the hands of Priscilla reached out to him and he reached back out and they held hands together in a rare transparent showing of sibling love.
****
It was the early morning and Priscilla had Duncan in her mouth already. Moving up and down on his shaft, she paused around his head, swirling her tongue around it as her brother stifled his moans. She moved down further as her tongue picked up on the veins in his dick. She pushed down deeper taking him into her throat as she experiment with what her brother liked. As she held him in her throat she felt the tale-tell thrashing and held him as he came in her mouth. Filling it with the warm, cloying taste of cum. She took it well as she swallowed it down.
It was after the first night that Duncan had told her about his 'super-boners' and where she was able to reveal that she had a 'super-pussy' one that was always wet and ready, constantly tuned on as long as she felt safe. Priscilla then brought up using each other for sexual gratification as neither of them had a current partner, Duncan had agreed. It was together they worked a small subtle symbols that could be used to indicate when it was safe to have sex with one another. As it was they could barely keep their hands off each other once they found out each was down for the other.
Aunt Theresa had taken their parents out for a nice dinner as a thank you for letting them stay and Priscilla and Duncan had been assigned to watch the kids. The cousins had voted on watching a movie and they all curled up on the couch. It wasn't long before Priscilla had creeped her hand over to Duncan's crotch as his hand did the same to her area. They fooled around for a bit until one of the cousins asked for popcorn. They both left to grab some and soda during which they also escalated between them. Priscilla wasn't a big kisser, something about kissing Duncan didn't feel right, of course as she was driven further by lust and passion she couldn't keep her lips off him.
As Priscilla reached up to grab the bags of popcorn she felt him push against her, his bodyweight pinning her to the counter. She had wore a low shirt with no panties underneath and he slipped in easily. Priscilla tried to stifle her moan as he entered, barely putting the popcorn into the microwave and hitting the button before he started pumping into her. Not wasting any time, he thrusted into her as hard and fast as he could, Priscilla using the counter to steady her as he pounded her from behind. The popcorn popping was able to muffle some of the sounds as she moaned from his thrusts. It started in her legs and began to climb as her ass tensed and then she felt it in her arms and soon her whole body coiled like a spring and as Duncan kept his thrusts hard and fast she climbed and then release.
She felt the strength leave her body as she went limp, held by Duncan's bodyweight pressing her against the counter. Duncan kept going using his sister's now limp body as little more than a fleshlight as he fought for his own release. Her pussy was soaked as he continued to pushing and pull, he delivered a quick solid slap to her ass, willing her to tighten up. Like a vice, he felt it wrap around his cock and push him over the summit as he filled his sister.
Just in time as the microwave started beeping. Grabbing the bag of popcorn, a bowl, and the bottle of Dr. Pepper along with cups, they walked back into the room. They took them to the table, letting the cousins fight it out as they went back under the covers, Priscilla felt Duncan's fingers as he swirled around in her sex, mixing her own wetness and his cum, he lifted the finger to her lips. She took it willingly in her mouth, sucking it gently and enthusiastically making sure that the cousin's attention was on the movie.
Settle back into comfortable positions they watched the rest of the movie.
The Belvilles would continue this even long after Aunt Theresa and their cousins had left. Every time they would come home from university without someone they would jump on another thinking it safer and easier than finding someone else in their hometown for a hookup. Together they attempted and tried everything, Duncan discovered he enjoyed anal play and Priscilla realized she wasn't the biggest fan of things going up her ass. They did roleplay, bondage, thinking it best to help each other find out what the other might like.
Duncan was the first to have to end it as he met someone who would eventually end up as his wife and aside from a Thanksgiving threesome where the wine had gotten Duncan's wife particularly rowdy there was no repetition of the Belville siblings. Priscilla eventually met her own husband and they regularly found reasons to visit each other, especially when they had kids. The truth was that the bed incident was the best thing for Duncan and Priscilla's relationship having grown closer from it.
Duncan smiled, thinking fondly as he did ever so often about him and his sister's sexploits together. A smell of freshly popped popcorn filling the room as his wife slide in next to him as they started the movie. Duncan thinking mischievously crept his hand over, unto to her thigh and, moving more daringly as their kids were around, towards her pussy.
He felt no resistance and only the reddening of her cheeks and the wetness he could start to feel accumulating the only indication that something was happening. He moved expertly, as the movie nights were common and he had more than enough practice fooling around under covers. Duncan pulled one leg over his for more room to play. Duncan kissed her as he moved in on her, despite her squeals of protest that were quickly drowned out by her enthusiastically kissing him.
"Oh, come on." Hissed a voice over to his right.
"Just be mad that you didn't try first." Duncan shot back at his sister, still mounted over his wife.
Priscilla rolled her eyes and turned over back to the movie. Duncan was able to see the subtle signs that she was getting fingered underneath her blankets. He chuckled at how nothing changes as he went back to trying to pork his wife, not stopped by the protests of the fingering couple next to them.
